Given numbers are 218, 532, 978, 947

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(218, 532) = 57988

GCD(218, 532) = ( 218 x 532 ) / 57988

= 218 / 532

= 218

Step2:

LCM(2, 978) = 978

GCD(2, 978) = ( 2 x 978 ) / 978

= 2 / 978

= 2

Step3:

LCM(2, 947) = 1894

GCD(2, 947) = ( 2 x 947 ) / 1894

= 2 / 947

= 2

So, Greatest Common Divisor of 218, 532, 978, 947 is 1
